We only recommend collagen that’s free of pesticides, chemicals, and heavy metals. From that list, we’ve identified the ones which also have no zinc. Here they are:
| Collagen | Zinc | Heavy Metals | Pesticides |
|---|---|---|---|
| Puori - CP1 Pure Collagen Peptides Powder | None | None | None |
| Perfect Supplements – Perfect Hydrolyzed Collagen Powder | None | Minor | No Glyphosate |
| Great Lakes Wellness Collagen Peptides Powder | None | Minor | No Glyphosate |
| Sports Research Collagen Powder | None | Minor | No Glyphosate |
Our favorite is Puori, since it has been tested to have zero heavy metals in it.

Keep the heavy metals in the factory, not in the collagen
One problem that collagen powders are prone to is heavy metal contamination. It seems to be the norm, according to independent testing, to find some amount of heavy metals in collagen. Lead, cadmium, arsenic, and mercury were the ones tested, and they were found in many collagen brands. However Puori has none, and the other brands on our list only have minor contamination, which is a lot better than the norm. And of course none of these collagen brands have any zinc in them.
Keep the pesticides out too
Collagen is a major risk for pesticide consumption, most likely. Pesticide in a cow’s diet gets stored in the parts that your collagen powder is made from. Industrial agriculture cows have something like 100 micrograms of glyphosate (a very nasty pesticide) per kilogram of their collagen. (Source) If you want to avoid eating that, you should stick to collagen powders that are independently certified to be glyphosate-free.
All the lab results for these collagen powders
Here are the results showing that these collagen powders have no glyphosate and minimal heavy metals in them. The ingredients list on the side of each product shows that the collagen has no zinc in it either.

In conclusion
Finding collagen without zinc is pretty easy. All you have to do is look on the side of the can. The products here all have no zinc. But it’s very important for your health to not consume chemicals and metals on a daily basis. That’s why these collagen products are not only zinc-free, they also are free of nasty chemicals like glyphosate and harmful metals like lead. We hope this article helped you!
